To compile my application I need to use the Flex and Bison applications. To
compile under Linux, all I need to do in my CMakeLists.txt file to find them is
find_package(FLEX REQUIRED)
find_package(BISON REQUIRED)
...and everything works as expected.
In Windows, however, I'm using the Cygwin versions of Flex and Bison which are
installed in C:\cygwin64\bin. This doesn't seem to be on the path that
find_package searches in Module Mode, so the search returns unsuccessfully.
However, if I try to tell find_package where to look, viz.
find_package(FLEX REQUIRED PATHS C:/cygwin64/bin NO_DEFAULT_PATH)
find_package(BISON REQUIRED PATHS C:/cygwin64/bin NO_DEFAULT_PATH)
...then by adding the PATHS keyword I've invoked Config mode and I get an error
message saying:
Could not find a package configuration file provided by "FLEX" with any of
the following names
FLEXConfig.cmake
flex-config.cmake
...because sure enough Cygwin does not provide these files.
So what can I do? Ideally I'd like to use Module Mode but provide a path hint;
but there seems no way to do that.
At the moment I can only think of:
(a) Hard-coding add_custom_target commands to invoke flex and bison entirely
manually when they're needed, or
(b) Writing my own FLEXConfig.cmake and BISONConfig.cmake files for use in
Config Mode.
Both of these seem disproportionately difficult for what seems to me like it
ought to be a common and simple problem. So is there a better solution that I'm
missing?
