Hi Robert, As my answer to Olaf seems could not be posted, I quote part of my answer to Olaf for your reference :
[ I have experience in OpenCV that after CMake have created the out-of-source build directory for OpenCV, I could only use "make" to build OpenCV but NO need to use "make install" to install OpenCV into my system. I could then use "FIND_PACKAGE( OpenCV REQUIRED )" and specify the "OpenCV_DIR" CMake variable to create new CMake projects that use the OpenCV library. I have used this approach for some times. I just wonder whether OpenSceneGraph could have a similar approach for CMake projects that use its libraries.] Regards Lawrence On Thu, Apr 19, 2012 at 11:19 PM, Lawrence Tsang <[email protected]> wrote: > Hi Robert, > > Thanks for the answer.
