CMake does not support the install target about lexy HOT 5 CLOSED

I'm not sure. Is it possible to use the commit hash as a version number? Because that's the only one the project has at the moment.

from lexy.

This will fetch the current commit hash, which you can then pass to the project command.

execute_process(
    COMMAND "git" "rev-parse" "--short" "HEAD"
    WORKING_DIRECTORY ${CMAKE_CURRENT_SOURCE_DIR}
    RESULT_VARIABLE LEXY_VERSION
    OUTPUT_QUIET
)

from lexy.

I don't think that works, the version has to be integers separated by dots: https://cmake.org/cmake/help/latest/command/project.html?highlight=project#options

from lexy.

You could convert the result into a decimal.

execute_process(
    COMMAND "git" "rev-parse" "--short" "HEAD"
    WORKING_DIRECTORY ${CMAKE_CURRENT_SOURCE_DIR}
    OUTPUT_VARIABLE LEXY_VERSION
    OUTPUT_STRIP_TRAILING_WHITESPACE
)
math(EXPR LEXY_VERSION "0x${LEXY_VERSION}" OUTPUT_FORMAT DECIMAL)

from lexy.

Yeah, that seems like too much magic. I'm closing this for now and will revisit it once I'm closer to an actual stable release.
