If I use environment variables in "Other CMake Arguments" it will replace the variables in an incorrect order. It needs to replace long names before short names.

Example:
The following variables exists:
MERCURIAL_REVISION = 0c775e18b569d4c5b505bd5fb73b854d700247d8
MERCURIAL_REVISION_BRANCH = default
MERCURIAL_REVISION_NUMBER = 5543
MERCURIAL_REVISION_SHORT = 0c775e18

If I use _BRANCH, _NUMBER or _SHORT it will replace half of the variable with the content of MERCURIAL_REVISION:

"0c775e18b569d4c5b505bd5fb73b854d700247d8_NUMBER" instead of "5543"
