[CMake] Windows registry subtree?

[Pau Garcia i Quiles]

Hello,

With GET_FILENAME_COMPONENT, I can get a key value:

GET_FILENAME_COMPONENT( QT4_ROOTDIR
[HKEY_LOCAL_MACHINE\SOFTWARE\Trolltech\Versions\4.5.2;InstallDir]
ABSOLUTE ))

Is it possible to get the keys in a subtree (i. e. all the registry
tree from a given folder)? Something like this:

GET_FILENAME_COMPONENT( QT4_VERSIONS
[HKEY_LOCAL_MACHINE\SOFTWARE\Trolltech\Versions;*] ABSOLUTE ))

Then get this list:

HKEY_LOCAL_MACHINE\Software\Trolltech\Versions;HKEY_LOCAL_MACHINE\Software\Trolltech\Versions\4.5.2;HKEY_LOCAL_MACHINE\Software\Trolltech\Versions\4.5.2\InstallDir;HKEY_LOCAL_MACHINE\Software\Trolltech\Versions\4.6.0;HKEY_LOCAL_MACHINE\Software\Trolltech\Versions\4.6.0\InstallDir

I. e. the result of invoking "reg query
HKLM\Software\Trolltech\Versions /s" but only the keys, not the
results.
