Can you help me?

for a reason I don't understand, when running CMAKE, the variable CMAKE_BINARY_DIR is empty. Thus cmake_install.cmake is wrongly generated.

[gaaned92]

I made a hack, using CMAKE_CURRENT_BINARY_DIR instead of CMAKE_BINARY_DIR in CMakeLists.txt and it works. So I think it can be closed.
