[CMake] Install destination problem

[Kris Thielemans]

Hi

 

My guess is that you have a local variable CMAKE_INSTALL_PREFIX being shadowed by the global variable. Best to add the CACHE keyword etc in your set statement, then there’ll be only 1 variable.

In all of my CMakeLists.txt files, I include a settings file, like so:

 

include(global_settings.cmake)

 

Inside global_settings.cmake, I have a line like this:

 

set( CMAKE_INSTALL_PREFIX ${CMAKE_BINARY_DIR}/install )

 

When I run "make install" on my development system, the files are correctly installed where I expect to find them, in a subdirectory of my build directory named "install".

 

But when I tried to do the same on our production server just now, it tried to install the binaries into /usr/local/bin.

 

It's as if $CMAKE_INSTALL_PREFIX did not get set.

 

What am I doing wrong?
