Is there a way to override CMAKE_INSTALL_PREFIX in a multi-level
CMake project? Since my package has a long history of being
installed in a location other than /usr/local, I really want to have
the default match previous practice.
For example, I have a source tree that looks like this:
root_dir
src
lib
In the root_dir/CMakeLists.txt file I set:
SET(CMAKE_INSTALL_PREFIX "/usr/thispkg" CACHE PATH "Prefix prepended
to install directories")
However this default setting does not show up when running ccmake or
cmake.
Changing this to:
SET(CMAKE_INSTALL_PREFIX "/usr/thispkg")
causes the value to show up in the root cmake_install.cmake file but
nowhere else.
What is the appropriate way of doing this?
