I'm hitting this is on 64-bit Linux (Ubuntu 12.04).
Simple CMakeLists.txt file:
cmake_minimum_required(VERSION 2.8)
project(Blah)
find_package(OpenGL REQUIRED)
message("OPENGL_INCLUDE_DIRS is ${OPENGL_INCLUDE_DIRS}")
message("OPENGL_LIBRARIES is ${OPENGL_LIBRARIES}")
Doing a regular "cmake .." works, but adding "-G Ninja" fails:
mikesart@mikesart64:~/data/src/bin64/Debug$ cmake .. -G Ninja
-- The C compiler identification is Clang 3.3.0
-- Check for working C compiler using: Ninja

CMake Error at
/usr/local/share/cmake-2.8/Modules/FindPackageHandleStandardArgs.cmake:97
(message):
Could NOT find OpenGL (missing: OPENGL_gl_LIBRARY)

If I explicitly set CMAKE_LIBRARY_ARCHITECTURE it will succeed:
cmake .. -G Ninja -DCMAKE_LIBRARY_ARCHITECTURE="x86_64-linux-gnu"
If anyone has any suggestions on better ways around this issue, I'd love to
hear them. Thanks much.
