I'm writing a CMakeLists.txt file, and I'm having problems getting find_package to choose libraries under /opt/local rather than /usr/local. Specifically, I've installed libarchive using macports and CMake cannot find it. When CMake configuration finds the the library in /usr/lib (/usr/lib/libarchive.dylib) but no corresponding header, it fails, and I would like to find a way to tell CMake to fall back to /opt/local, where a version of the library as well as the archive.h header is installed.
I'm new to CMake, and I've spent some time researching this question on google, stackoverflow, and recent archives for this list. It seems like a situation that would come up often but I haven't found a solution that works for me yet. I have the most recent versions of CMake (binary install) and macports on my system. macports packages are found under /opt/local. I am glad to try to solve the problem and contribute changes to CMake, but I'm guessing there is some easier way. Solutions tried I've so far: Based on other related posts, I've tried things like declaring INCLUDE_DIRECTORIES(/opt/local/include) and LINK_DIRECTORIES(/opt/local/lib), with BEFORE, SYSTEM, and BEFORE SYSTEM, but /opt/local doesn't seem to be searched. Also I've tried set(CMAKE_LIBRARY_PATH /opt/local/lib ${CMAKE_LIBRARY_PATH}) and set(CMAKE_INCLUDE_PATH /opt/local/include ${CMAKE_INCLUDE_PATH}), also without results. The find_package file for libarchive (cmake-2.8/Modules/FindLibarchive.cmake) does not seem to make use of HINT, nor hardcode /opt/local (as seen in the corresponding boost file, for example.)
