CMAKE_CURRENT_BINARY_DIRΒΆ
The path to the binary directory currently being processed.
This the full path to the build directory that is currently being
processed by cmake. Each directory added by add_subdirectory() will
create a binary directory in the build tree, and as it is being
processed this variable will be set. For in-source builds this is the
current source directory being processed.
When run in -P script mode, CMake sets the variables
CMAKE_BINARY_DIR, CMAKE_SOURCE_DIR,
CMAKE_CURRENT_BINARY_DIR and
CMAKE_CURRENT_SOURCE_DIR to the current working directory.
