Hi Brad,
I'm pretty sure something changed in the the interpretation of variables. I
attached a simple CMakeLists.txt file that shows the difference along with a
configuration file to read in.
In Cmake 2.0.6 it runs fine. In Cmake 2.4.2 it fails when reading the
configuration file. The backslashes in the last line need to be escaped. Also,
in the first line the ${...} string is not replace with the variable's
contents. That's what causes the test to fail.
Note that the CMakeLists.txt program copies each word in ${line} into a
WordList variable. It's pretty useless in the test program, but in our
configuration it actually filters out some important keywords. If I skip that
step in the test program, the test fails with Cmake 2.0.6, so I asume that the
variable interpretation was done in that step in the older Cmake.
Is there a way in Cmake 2.0.4 to force the interpretation of variables in
strings?
- Kris.
