Gtest with ITK_USE_SYSTEM_LIBRARIES

Engineering

Hi, just compiling ITK in new laptop and hitting the following, I have no gtest installed in the computer, but I do want to use other system libraries (fftw mainly)

cmake -G Ninja ../ITK-src \
-DExternalData_OBJECT_STORES:PATH=~/Software/ITK/ExternalData \
-DITK_USE_SYSTEM_LIBRARIES:BOOL=ON \
-DBUILD_SHARED_LIBS:BOOL=ON \
-DBUILD_SHARED_LIBS=ON \
-DBUILD_TESTING=OFF \
-DCMAKE_BUILD_TYPE=Release \
-DCMAKE_INSTALL_PREFIX:PATH=~/devtoolset/release/ITK \
-DITK_USE_FFTW:BOOL=ON -DITK_USE_FFTWD:BOOL=ON -DITK_USE_FFTWS:BOOL=ON -DITK_USE_FFTWF:BOOL=ON \
-DModule_IsotropicWavelets:BOOL=ON \
-DModule_ITKVtkGlue:BOOL=ON

CMake Error at /usr/share/cmake-3.11/Modules/FindPackageHandleStandardArgs.cmake:137 (message):

Shoudn’t cmake handle the case where gtest is not the in the system and download it?

Nevermind, seems the default behaviour. If I install gtest in the system, I get same error with HDF5.

I guess ITK_USE_SYSTEM_LIBRARIES requires all the libraries to be installed in the system.

That’s right. But you can specify individually which libraries are provided by the system. ITK_USE_SYSTEM_LIBRARIES is just a shortcut to set all the libraries with system variants to SYSTEM.
