测试找不到的内置静态库-CMAKE

Question

我正在尝试使用CMake在C ++中构建一个库。但是，我无法在正在测试的位置（使用googletest）中包含内置库的标头。

项目结构

• CMakeLists.txt
• 构建
• googletest
• sim
  • CMakeLists.txt
  • *。cpp
  • *。h
  • 测试
    • CMakeList.txt
    • *。cpp

CMakeLists.txt

cmake_minimum_required(VERSION 3.11)
project(Simulaton)

add_subdirectory(sim)
add_subdirectory(googletest)

enable_testing()

sim / CMakeLists.txt

file(GLOB SIM_SRCS *.cpp)
file(GLOB_RECURSE SIM_TEST_FILES test/*.cpp)
file(GLOB_RECURSE SIM_HEADERS *.h)

add_library(simulaton STATIC ${SIM_SRCS} ${SIM_HEADERS})

add_subdirectory(test)

install(TARGETS simulaton EXPORT sim DESTINATION lib)
install(DIRECTORY ${CMAKE_CURRENT_LIST_DIR}
  DESTINATION include
  FILES_MATCHING PATTERN ".h")

sim / test / CMakeLists.txt

file(GLOB_RECURSE SIM_TEST_FILES *.cpp)

add_executable(testrunner ${SIM_TEST_FILES})

target_link_libraries(testrunner simulaton gtest_main)

add_test(NAME testing COMMAND testrunner)

“ cmake ..”有效（或至少不会引发任何错误），但是 抛出：

/home/.../simulaton/sim/test/heaptest.cpp:25:10: fatal error: simulaton/heap.h: No such file or directory
#include <simulaton/heap.h>
      ^~~~~~~~~~~~~~~~~~
compilation terminated.

请注意，我可以成功包含/使用安装在同一位置的googletest
