Pull request overview
Enables consuming Box2D directly from its CMake build tree (without installation) by generating a build-directory box2dConfig.cmake and colocating the package version file where find_package(box2d) can resolve it when box2d_DIR is set to the build directory.
Changes:
- Add a build-tree
export(EXPORT ...)to emitbox2dConfig.cmakeinto${PROJECT_BINARY_DIR}. - Move
box2dConfigVersion.cmakegeneration and installation source path from${CMAKE_CURRENT_BINARY_DIR}to${PROJECT_BINARY_DIR}.
