Windows上具有Flex / Bison的Cmake

Question

I downdloaded this flex/bison executables. I copied them to C:\\Program Files\\Flex-Bison . I also added this dir to Path When using this buildscript, how can I make CMake find the executables in this folder?

CMAKE_MINIMUM_REQUIRED(VERSION 3.8.2)

find_package(FLEX)
if(NOT FLEX_FOUND)
    message(SEND_ERROR "Flex not found")
endif()

find_package(BISON)
if(NOT BISON_FOUND)
    message(SEND_ERROR "Bison not found")
endif()

Answer 1

I checked FindFlex and FindBISON CMake modules and they don't seem to use the usual <package>_DIR and <package>_ROOT hints (the latter would also have been useful for find_program , which has a mode to utilize that).

So, the easiest solution would be to place both executables in your PATH variable, which will allow their invocation from anywhere. Otherwise, you may also amend that PATH with a custom location of your choice.
