CMAKE_CACHEFILE_DIR
|
||||
-------------------
|
||||
|
||||
The directory with the ``CMakeCache.txt`` file.
|
||||
|
||||
This is the full path to the directory that has the ``CMakeCache.txt``
|
||||
file in it. This is the same as :variable:`CMAKE_BINARY_DIR`.
|
||||
This variable is used internally by CMake, and may not be set during
|
||||
the first configuration of a build tree. When it is set, it has the
|
||||
same value as :variable:`CMAKE_BINARY_DIR`. Use that variable instead.
