CMake preload script for cache

Question

I fire cmake with the -C mysettings.cmake.

The content of myfile.cmake is

set(CMAKE_INSTALL_PREFIX "C:/install/mylib" STRING)

Everything is generated but it seems the -C mysettings.cmake variable is not set. It is still installed in the default directory.

Cmake prints the message "loading initial cache file ../../script/cmake/mysettings.cmake" without any error.

The full call:

cmake -C ../../script/cmake/mysettings.cmake -G "Visual Studio 9 2008" ../../source/mylib

Is there something wrong with my syntax?

The given file should be a CMake script containing SET commands that use the CACHE option, not a cache-format file.

So your myfile.cmake needs to look something like this:

set(CMAKE_INSTALL_PREFIX "C:/install/mylib" CACHE PATH "")
