If you have an eigen.cmake from Eigen, but CMake isn't seeing it, you may need to update your CMake module path so CMake can find the file. View entire discussion ( 2 comments) More posts from the cmake community. Posted by 1 day ago. How to use install command. In Module mode, CMake searches for a file called Find.cmake. The file is first searched in the CMAKEMODULEPATH, then among the Find Modules provided by the CMake installation. If the file is found, it is read and processed by CMake. It is responsible for finding the package, checking the version, and producing any needed messages.

- Hi!I’ve got an error as follows.
Would anyone help me?
Thanks in advance.* Windows 7(64bit), Visual studio 2012, cmake 3.2.3
SOFA is latest version(I downloaded it today from git)
CMake Error at SofaFramework/CMakeLists.txt:169 (find_package):
By not providing “FindEigen3.cmake” in CMAKE_MODULE_PATH this project has
asked CMake to find a package configuration file provided by “Eigen3”, but
CMake did not find one.Could not find a package configuration file provided by “Eigen3” with any
of the following names:Eigen3Config.cmake
eigen3-config.cmakeAdd the installation prefix of “Eigen3” to CMAKE_PREFIX_PATH or set
“Eigen3_DIR” to a directory containing one of the above files. If “Eigen3”
provides a separate development package or SDK, be sure it has been
installed.Configuring incomplete, errors occurred!Dear Jo,I am not working on Windows but did you try to set a variable “Eigen3_DIR” to the path: PATH_TO_SOFA/extlibs/eigen-3.2.7 in the Cmake configuration ?Let us know if it helps.Cheers,HugoHi Jo,CMake is supposed to auto-detect Eigen libs.
They are in YOUR_SOFA_DIR/extlibs/eigen-3.2.7After running “Configure” in CMake-GUI, search for “eigen”.
You should find these two entries :If they are not well set, try to set them yourself and re-run “Configure”.Regards,
Guillaume.Hmm looks strange.
I will let the developers know about this, and come back to you asap.Cheers,HugoEven before checking the Eigen3 variables, the error message
“By not providing “FindEigen3.cmake” in CMAKE_MODULE_PATH this project has
asked CMake to find a package configuration file provided by “Eigen3”, but
CMake did not find one.”
is already awkward.Can you check that you have the file FindEigen3.cmake in the cmake/Modules directory ?Hello,The fact you dont have a folder named “Modules” in your cmake is really weird (it is where all our custom cmake scripts are located so if you dont have it, CMake wont be able to detect anything, such as Eigen).I just tried the instructions from the website to fetch the code
(executing git clone -b master git://scm.gforge.inria.fr/sofa/sofa.git with master and v15.12 branches) and I got the complete source, with contents in the directory cmake/Modules.
Maybe there was a problem when you cloned the repo ?
git might have failed and your source tree is incomplete ? Can you try again the cloning process ?Hi Jo,Glad to see you solved your problem !Indeed, separating source from build directory in a very clean way is one of CMake super-powers (but I didn’t know it was necessary).
It allows you to manage easily as many builds as you want from the same source (debug build, release build, GCC build, Clang build, …).Do not hesitate to come back on the forum if you have other questions.Regards,
Guillaume.PS: Many thanks to Hugo and Froy who helped on this topic. ?
Cmake eigen3

CMake is a cross-platform tool to generate files for your platform's native build system. For example, on Unix it generates Makefiles (so you Anyhow, setting EIGEN3_INCLUDE_DIR is totally unrelated to the location of FindEigen3.cmake However, it could be that your FindEigen3 script evaluates this variable to determine the location of your Eigen3 installation. Alternatively, self-built CMake-based projects often provide a <PackageName>Config.cmake.
Since Eigen3 is completely header only, all you ever need is the path to the include directory. And this one, you are already defining manually Adjust CMAKE_MODULE_PATH to find FindEigen3.cmake or set Eigen3_DIR to the directory containing a CMake configuration file for Eigen3. The file will have one of the following names: Eigen3Config.cmake eigen3-config.cmake However, I didn't find either of those files in either the source dir or build dir of Eigen3.
Cmake eigen include directories
CMake will produce project files that generate an executable called example which requires at least version 3.3 of Eigen. Here, path-to-example-directory is the path to the directory that contains both CMakeLists. txt and example. The difference from directly including the /usr/include/eigne3 or /usr/local/include/eigen3 directory is that, a configuration directory called eigen3/cmake will also be installed to /usr/share or usr/local/share. This configuration directory contains the Eigen3Config.cmake file, which can automatically be found by CMake to locate the eigen3 directory.

cmake-developer(7), Find Modules¶. A “find module” is a Find<PackageName>.cmake file to be loaded by the find_package Find Modules ¶. A “find module” is a Find<PackageName>.cmake file to be loaded by the find_package () command when invoked for <PackageName>. The primary task of a find module is to determine whether a package exists on the system, set the <PackageName>_FOUND variable to reflect this and provide any variables, macros and imported targets required to use the package.
find_package, Many find-modules provide limited or no support for versioning; check the module documentation. If no module is found and the MODULE option is not given the This fall back is disabled if the MODULE option is given. In Module mode, CMake searches for a file called Find<PackageName>.cmake . The file is first searched in the CMAKE_MODULE_PATH , then among the Find Modules provided by the CMake installation. If the file is found, it is read and processed by CMake.
