我使用的这个科学应用程序使用cmake来构建它的程序。附件是CMakeLists.txt:
cmake_minimum_required(VERSION 2.8)
set(PROJECT_NAME myproject)
project(${PROJECT_NAME})
# Set verbose output while testing CMake
#set(CMAKE_VERBOSE_MAKEFILE 1)
# Set CMake behavior
cmake_policy(SET CMP0004 OLD)
# Get DOLFIN configuration data (DOLFINConfig.cmake must be in
# DOLFIN_CMAKE_CONFIG_PATH)
find_package(DOLFIN)
# Need to get VTK config because VTK uses advanced VTK features which
# mean it's not enough to just link to the DOLFIN target. See
# http://www.vtk.org/pipermail/vtk-developers/2013-October/014402.html
find_package(VTK HINTS ${VTK_DIR} $ENV{VTK_DIR} NO_MODULE QUIET)
# Default build type (can be overridden by user)
if (NOT CMAKE_BUILD_TYPE)
set(CMAKE_BUILD_TYPE "RelWithDebInfo" CACHE STRING
"Choose the type of build, options are: Debug MinSizeRel Release RelWithDebInfo." FORCE)
endif()
# Compiler definitions
add_definitions(${DOLFIN_CXX_DEFINITIONS})
# Compiler flags
set(CMAKE_CXX_FLAGS "${DOLFIN_CXX_FLAGS} ${CMAKE_CXX_FLAGS}")
# Include directories
include_directories(${DOLFIN_INCLUDE_DIRS})
include_directories(SYSTEM ${DOLFIN_3RD_PARTY_INCLUDE_DIRS})
# Executable
add_executable(${PROJECT_NAME} main.cpp)
# Target libraries
target_link_libraries(${PROJECT_NAME} ${DOLFIN_LIBRARIES})
但是,我需要包含一些不包含在DOLFIN中的额外编译器标志和库。我需要加入名为PAPI的这个包。在我的系统上,路径/环境是:
PAPI_LIBDIR=/project/cacds/apps/papi/5.4.0/lib
PAPI_INCLUDE=/project/cacds/apps/papi/5.4.0/include
PAPI_FLAG=-lpapi
通常我会做这样的事情:
gcc -O3 -o -I myproject $(PAPI_LIBDIR) main.c -L $(PAPI_INCLUDE) $(PAPI_FLAG)
但我还需要额外的DOLFIN库和第三方软件包。请原谅我这是一个愚蠢或简单的问题,但我如何修改上面的CMakeLists.txt?我是cmake的新手,所以任何帮助表示赞赏,谢谢
答案 0 :(得分:4)
最干净的解决方案是创建FindPAPI.cmake
。因此,将此文件添加到项目中cmake/
文件夹:
<强> FindPAPI.cmake 强>
# Try to find PAPI headers and libraries.
#
# Usage of this module as follows:
#
# find_package(PAPI)
#
# Variables used by this module, they can change the default behaviour and need
# to be set before calling find_package:
#
# PAPI_PREFIX Set this variable to the root installation of
# libpapi if the module has problems finding the
# proper installation path.
#
# Variables defined by this module:
#
# PAPI_FOUND System has PAPI libraries and headers
# PAPI_LIBRARIES The PAPI library
# PAPI_INCLUDE_DIRS The location of PAPI headers
find_path(PAPI_PREFIX
NAMES include/papi.h
)
find_library(PAPI_LIBRARIES
# Pick the static library first for easier run-time linking.
NAMES libpapi.a papi
HINTS ${PAPI_PREFIX}/lib ${HILTIDEPS}/lib
)
find_path(PAPI_INCLUDE_DIRS
NAMES papi.h
HINTS ${PAPI_PREFIX}/include ${HILTIDEPS}/include
)
include(FindPackageHandleStandardArgs)
find_package_handle_standard_args(PAPI DEFAULT_MSG
PAPI_LIBRARIES
PAPI_INCLUDE_DIRS
)
mark_as_advanced(
PAPI_PREFIX_DIRS
PAPI_LIBRARIES
PAPI_INCLUDE_DIRS
)
然后,修改您的CMakeLists.txt:
cmake_minimum_required(VERSION 2.8)
set(PROJECT_NAME myproject)
project(${PROJECT_NAME})
set(CMAKE_MODULE_PATH "${CMAKE_MODULE_PATH};${CMAKE_CURRENT_SOURCE_DIR}/cmake")
find_package(PAPI REQUIRED)
...
# Include directories
include_directories(${DOLFIN_INCLUDE_DIRS})
include_directories(SYSTEM ${DOLFIN_3RD_PARTY_INCLUDE_DIRS})
include_directories(${PAPI_INCLUDE_DIRS})
# Executable
add_executable(${PROJECT_NAME} main.cpp)
# Target libraries
target_link_libraries(${PROJECT_NAME} ${PAPI_LIBRARIES} ${DOLFIN_LIBRARIES})
我希望它能解决它! ;)
