Eigen cmake library wrapper, because official cmake is 💩
# ⬇️ Download project from Github
git clone https://github.com/Naostage/eigen.cmake
cd eigen.cmake
# 🔧 Configure project
cmake -E make_directory build
cmake \
-DEIGEN_ENABLE_EXAMPLES=ON `# 🚀 Enable Examples (eigen_example)` \
-DEIGEN_ENABLE_INSTALL=ON `# 📦️ Enable Install` \
-DEIGEN_ENABLE_FIND_PACKAGE=ON `# Enable find_package before cpm` \
-B build -S .
# 🔨 Build:
cmake --build build --target eigen_example --config Release -j12
# 📦️ Install library (You can control installation path with -DCMAKE_INSTALL_PREFIX=mypath)

When using CPM, adding eigen.cmake to your project is as simple as:
CPMAddPackage(
NAME eigen.cmake
GIT_REPOSITORY "https://github.com/Naostage/eigen.cmake"
GIT_TAG "v3.4.0"
)
target_link_libraries(mytarget PRIVATE Eigen3::Eigen)One the library is installed you can simply:
find_package(Eigen3 REQUIRED)
target_link_libraries(mytarget PRIVATE Eigen3::Eigen)Complete example can be found in examples/install.
