[CMake] How to read a registry key?
Hello,
I have found that using EXEC_PROGRAM with ${CMAKE_COMMAND} -E I can
write/remove a key in the Windows registry but I haven't figured out how
to read a key. Is there a simple solution for that?

Sure, but it seems not to be documented
Several commands including GET_FILENAME_COMPONENT will expand things
like this:
"[HKEY_LOCAL_MACHINE\\SOFTWARE\\JavaSoft\\Java Development
Kit\\2.0;JavaHome]/bin"
You can use this to read registry values. I will add some docs in
the morning.

Re: [CMake] How to read a registry key?
Bill,
I had some success with the key expansion but I haven't been able to do
what I need. Basically, I would like to get the un-expanded content of
the user path, i.e. not the expanded path (user and system) which can be
found using $ENV{PATH}.
I tried the following code, i.e. adding two variables, one using the
other:
SET(CISST_PATH ${EXECUTABLE_OUTPUT_PATH} ${LIBRARY_OUTPUT_PATH})
SET(CISST_PATH_REG_KEY "HKEY_CURRENT_USER\\Environment;CISST_PATH")
EXEC_PROGRAM(${CMAKE_COMMAND}
ARGS "-E write_regv \"${CISST_PATH_REG_KEY}\"
\"${CISST_PATH}\"")
SET(OTHER_PATH_REG_KEY "HKEY_CURRENT_USER\\Environment;OTHER_PATH")
SET(OTHER_PATH "c:/prg;%CISST_PATH%")
EXEC_PROGRAM(${CMAKE_COMMAND}
ARGS "-E write_regv \"${OTHER_PATH_REG_KEY}\"
\"${OTHER_PATH}\"")
GET_FILENAME_COMPONENT(TMP "[HKEY_CURRENT_USER\
\Environment;OTHER_PATH]/dummy.dum" PATH)
MESSAGE("${TMP}")
At that point, everything looks great and I can check the results with
"reg.exe", the expansion works ...
Now, if I try to retrieve the user path using
GET_FILENAME_COMPONENT(TMP "[HKEY_CURRENT_USER\
\Environment;PATH]/dummy.dum" PATH)
TMP is set to "/registry" ... Any explanation or better solution to
just retrieve the value as a string?

Re: [CMake] How to read a registry key?
I looks like this has something to do with the nature of the key/value.
For values listed as REG_SZ (within regedit.exe), CMake can retrieve the
content but for values stored as REG_EXPAND_SZ I systematically get
"/registry". I don't know much about the Windows registry but I did a
quick survey of different computers/users in the lab and the user path
can be either one which makes it difficult to implement a robust
solution. Am I the first one to run into this issue?
