Trying to set Flex/Bison location

[rvkennedy]

I have win_flex.exe and win_bison.exe. I've tried setting the paths to these as environment variables (set FLEX_EXECUTABLE=C:\Dropbox\Programs\win_flex_bison\win_flex.exe), as lines at the top of CmakeLists.txt (SET(BISON_EXECUTABLE "C:/Dropbox/Programs/win_flex_bison/win_bison.exe" CACHE PATHFILE "bison")) and as lines in the main body of CmakeLists.txt (as above). In each case, we get the same error as if they were unset. What is the correct way to do this?

my working way of setting environment variables is through the cmake-gui
you could also edit your CMakeCache.txt i think

entries in my cache file:

//path to the bison executable
BISON_EXECUTABLE:FILEPATH=E:/Programming/GnuWin32/bin/bison.exe

//path to the flex executable
FLEX_EXECUTABLE:FILEPATH=E:/Programming/GnuWin32/bin/flex.exe

good luck!

Thanks - I think the "FILEPATH=" is what I'm missing!
