On a Windows 7 machine I cannot read any registry values that contain a semicolon.
For example if you have 7-zip, running the following
SET(MYPATH [HKEY_LOCAL_MACHINE\SOFTWARE\7-Zip;Path])
MESSAGE("MYPATH = ${MYPATH}")
results in
MYPATH = [HKEY_LOCAL_MACHINESOFTWARE7-Zip;Path]
instead of the actual path as per the following thread. I think cmake support for registry paths that contain ";" are broken on Windows 7. Can somebody confirm this? Is there any work-around?
