CMake - check if Pylint is installed
2 answers
You should create a FindPylint.cmake file and include()
directory. Then run find_package(Pylint REQUIRED)
.
FindPylint.cmake:
execute_process(
COMMAND pylint --version
OUTPUT_VARIABLE pylint_out
RESULT_VARIABLE pylint_error
ERROR_VARIABLE pylint_suppress)
if (NOT pylint_error)
string(REGEX MATCH "pylint .\..\.." pylint_version_string "${pylint_out}")
string(SUBSTRING "${pylint_version_string}" 7 5 pylint_version)
endif ()
if (pylint_version)
set(PYLINT_FOUND 1
CACHE INTERNAL "Pylint version ${pylint_version} found")
endif ()
include(FindPackageHandleStandardArgs)
find_package_handle_standard_args(Pylint REQUIRED_VARS pylint_version
VERSION_VAR pylint_version)
Some explanation:
- The output error is not actually an error, it reads
No config file found, using default configuration
, so we suppress it by ignoring the variablepylint_suppress
. - the output
pylint
has more than just a version, so we need to do some regex / string processing. - the variable is
CACHE INTERNAL
not strictly necessary, but may be useful later to check if Pylint is found.

CMakeLists.txt
list(APPEND CMAKE_MODULE_PATH ${CMAKE_CURRENT_SOURCE_DIR})
find_package ( Pylint )
if ( PYLINT_FOUND )
message ( STATUS "pylint version: ${PYLINT_VERSION}" )
endif ()
And in the same directory add FindPylint.cmake :
# - Find Pylint
# Find the Pylint executable and extract the version number
#
# OUTPUT Variables
#
# PYLINT_FOUND
# True if the pylint package was found
# PYLINT_EXECUTABLE
# The pylint executable location
# PYLINT_VERSION
# A string denoting the version of pylint that has been found
find_program ( PYLINT_EXECUTABLE pylint PATHS /usr/bin )
if ( PYLINT_EXECUTABLE )
execute_process ( COMMAND ${PYLINT_EXECUTABLE} --version OUTPUT_VARIABLE PYLINT_VERSION_RAW ERROR_QUIET )
if (PYLINT_VERSION_RAW)
string ( REGEX REPLACE "^pylint ([0-9]+.[0-9]+.[0-9]+),.*" "\\1" PYLINT_VERSION ${PYLINT_VERSION_RAW})
else ()
set ( PYLINT_VERSION "unknown" )
endif()
endif ()
include(FindPackageHandleStandardArgs)
FIND_PACKAGE_HANDLE_STANDARD_ARGS ( Pylint DEFAULT_MSG PYLINT_EXECUTABLE )
mark_as_advanced ( PYLINT_EXECUTABLE PYLINT_VERSION )
Based on this code .
