# This module is designed to find/handle editline library
|
|
#
|
|
# Requirements:
|
|
# - CMake >= 2.8.3 (for new version of find_package_handle_standard_args)
|
|
#
|
|
# The following variables will be defined for your use:
|
|
# - EDITLINE_INCLUDE_DIRS : editline include directory
|
|
# - EDITLINE_LIBRARIES : editline libraries
|
|
# - EDITLINE_VERSION : complete version of editline (x.y)
|
|
# - EDITLINE_MAJOR_VERSION : major version of editline
|
|
# - EDITLINE_MINOR_VERSION : minor version of editline
|
|
#
|
|
# How to use:
|
|
# 1) Copy this file in the root of your project source directory
|
|
# 2) Then, tell CMake to search this non-standard module in your project directory by adding to your CMakeLists.txt:
|
|
# set(CMAKE_MODULE_PATH ${PROJECT_SOURCE_DIR})
|
|
# 3) Finally call find_package(EditLine) once
|
|
#
|
|
# Here is a complete sample to build an executable:
|
|
#
|
|
# set(CMAKE_MODULE_PATH ${PROJECT_SOURCE_DIR})
|
|
#
|
|
# find_package(EditLine REQUIRED) # Note: name is case sensitive
|
|
#
|
|
# include_directories(${EDITLINE_INCLUDE_DIRS})
|
|
# add_executable(myapp myapp.c)
|
|
# target_link_libraries(myapp ${EDITLINE_LIBRARIES})
|
|
#
|
