CMAKE_CURRENT_BINARY_DIRΒΆ
The path to the binary directory currently being processed.
This is 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.
