Cmake doesn't respect value of CMAKE_INSTALL_PREFIX

I'm trying to install awesome wm from source. So I created a build directory and executed the following command:

cmake .. -DCMAKE_INSTALL_PREFIX=$PREFIX

But make install tries to put some of the program files in /usr/local/share, which isn't where I want them:

> make install
[  3%] Built target generated_sources
[  6%] Built target test-gravity

CMake Error at cmake_install.cmake:69 (file):

  file or directory


make: *** [Makefile:107: install] Error 1

Is there some cmake variable similar to CMAKE_INSTALL_PREFIX or CMAKE_INSTALL_LIBDIR which I need to specify for share data?

Solution

  • You'll have CMAKE_INSTALL_DATADIR for share when using the cmake module: include(GNUInstallDirs)

    Note: when using cmake --build build --target install -- DESTDIR=foo please read the CMAKE_INSTALL_PREFIX doc

    On UNIX one can use the DESTDIR mechanism in order to relocate the whole installation. DESTDIR means DESTination DIRectory.

    WARNING: DESTDIR may not be used on Windows because installation prefix usually contains a drive letter like in C:/Program Files which cannot be prepended with some other prefix.
