如何添加到CMake的包含路径？

Question

我尝试使用以下方式添加路径：

export PATH=<myPath>
export CPPFLAGS='-I<myPath>'

我尝试使用make -I=<myPath>运行make。但是make仍然看不到hpp个文件。

CmakeLists：

cmake_minimum_required(VERSION 2.4.6)
include($ENV{ROS_ROOT}/core/rosbuild/rosbuild.cmake)
rosbuild_init()
set(EXECUTABLE_OUTPUT_PATH ${PROJECT_SOURCE_DIR}/bin)
set(LIBRARY_OUTPUT_PATH ${PROJECT_SOURCE_DIR}/lib)
rosbuild_genmsg()
rosbuild_gensrv()
rosbuild_add_executable(add_two_ints_server src/add_two_ints_server.cpp)
rosbuild_add_executable(add_two_ints_client src/add_two_ints_client.cpp)
rosbuild_add_executable(data_sender src/data_sender.cpp)
rosbuild_add_executable(data_listener src/data_listener.cpp)
rosbuild_add_executable(dds_transfer src/dds_transfer.cpp)

MakeFile：

include $(shell rospack find mk)/cmake.mk

使用CMAKE_PREFIX_PATH，这是CMake搜索库的路径。请参见示例https://stackoverflow.com/a/41909627/2799037
