[CMake] Regex changes between cmake 2.0.6 and 2.4.2 ??

[Kris Dekeyser]

Hi Brad,

Yep, I just discovered what it is. The WordList entry actually starts with a ${var}. The text is read from a project configuration file with 
FILE(READ ${Configfile} ConfigFileContents)
When a [Headers] section is encountered, each line is processed. One of these lines contain:
${EDA_ROOT_DIR}/export/include

Now, in Cmake 2.0.6, the variable was interpreted and replaced with the correct path before the IF(... MATCHES ...) test. With Cmake 2.4.2 apparently not.

Does that make any sense?

- Kris
