首先我使用克利翁和内置的cmake在Ubuntu 17cmake错误：没有这样的文件？

构建按摩日志：

[ 20%] Linking C executable pacman 
cc: error: SDL2_image: No such file or directory 
CMakeFiles/pacman.dir/build.make:172: recipe for target 'pacman' failed 
make[3]: *** [pacman] Error 1 
CMakeFiles/Makefile2:67: recipe for target 'CMakeFiles/pacman.dir/all' failed

make[1]: *** [CMakeFiles/pacman.dir/rule] Error 2 
Makefile:118: recipe for target 'pacman' failed 
make: *** [pacman] Error 2

cmakeList.txt：

cmake_minimum_required(VERSION 3.9) 
project(pacman C) 
set(CMAKE_C_STANDARD 99) 
set(SOURCE src/main.c src/input.c src/input.h src/view.c src/view.h src/models.h src/models.c) 
add_executable(pacman "${SOURCE}") 
include_directories(src) 
include_directories(src/SDL2-2.0.7/include) 
INCLUDE(FindPkgConfig) 
PKG_SEARCH_MODULE(SDL2 REQUIRED sdl2) 
PKG_SEARCH_MODULE(SDL2IMAGE REQUIRED) 
set(SDL2_IMAGE_INCLUDE_DIR "src/SDL2_image-2.0.2") 
include_directories("${SDL2_IMAGE_INCLUDE_DIR}") 
target_link_libraries(pacman "${SDL2_LIBRARIES} ${SDL2IMAGE_LIBRARIES}")

和一个名为Makefile的文件：（我不太了解它！不幸的是，这个错误终于从这里升起）

# Makefile for showimage 
CC = gcc 
CFLAGS = $(shell sdl2-config --cflags) -Wall -O 
LIBS = $(shell sdl2-config --libs) -lSDL2_image 
EXE = showimage 
all: $(EXE) 
showimage: showimage.c Makefile 
    $(CC) -o [email protected] [email protected] $(CFLAGS) $(LIBS) 
clean: 
    -rm *.o $(EXE)

注意，我敢肯定，我已经安装使用这个命令所有SDL2库100％：

sudo apt-get install libsdl2*

和正确的工作，一切都完了，没有任何错误输出这样的：

感谢您的帮助beforehands :)））））

我已经通过以这种方式更改cmake代码修复了这一切： 只需手动给出sdl目录路径即可！

cmake_minimum_required(VERSION 3.9) 
project(pacman C) 
set(CMAKE_C_STANDARD 99) 
set(SOURCE src/main.c src/input.c src/input.h src/view.c src/view.h src/models.h src/models.c src/controler.c src/controler.h) 
add_executable(pacman "${SOURCE}") 
include_directories(src) 
include_directories("/usr/include/SDL2") 
target_link_libraries(pacman m SDL2 SDL2_gfx SDL2_image) 
ADD_DEFINITIONS(-D_REENTRANT)

回答：

使用find_library代替PKG_SEARCH_MODULE

find_library(SDL2_LIBRARY NAME SDL2) 
target_include_directories(pacman ${SDL2_INCLUDE_DIR}) 
target_link_libraries(pacman ${SDL2_LIBRARY})

如果找不到SDL2，则必须将SDL2的路径添加到CMAKE_PREFIX_PATH，即CMake查找已安装软件的位置。
