I'm working with C++ on Ubuntu and trying to make two targets with the help of cmake, one is the normal exe and the other is to run the unit-test. here is my project:
|---include
| |---Student.h
|
|---src
| |---Student.cpp
| |---main.cpp
|
|---unittest
| |---TestStudent.cpp
|
|---CMakeLists.txt # how to write this file?
Now the CmakeLists.txt is like this:
cmake_minimum_required(VERSION 3.9)
project(Student CXX)
set(CMAKE_CXX_COMPILER g++)
set(CMAKE_CXX_STANDARD 11)
set(SOURCES src/Student.cpp)
set(INCLUDES include)
find_package(GTest REQUIRED)
add_executable(student src/main.cpp ${SOURCES})
target_include_directories(student PRIVATE ${INCLUDES})
target_compile_options(student PRIVATE -std=c++11 -g)
add_executable(student-test unittest/TestStudent.cpp ${SOURCES})
target_include_directories(student-test PRIVATE ${INCLUDES})
target_compile_options(student-test PRIVATE -std=c++11 -g -O0)
target_link_libraries(student-test -lgtest -lpthread -fprofile-arcs -ftest-coverage)
enable_testing()
include(GoogleTest)
gtest_add_tests(TARGET student-test AUTO)
So, after executing mkdir build && cd build && cmake .. && make, two executable files are generated: student and student-test. However, when I execute ./student-test, the raw coverage file isn't generated. But if I compile it with the pure command: g++ -std=c++11 TestStudent.cpp ../src/Student.cpp -I ../include/ -lgtest -lpthread -fprofile-arcs -ftest-coverage -g -O0 -o student-test, it works without any problem, meaning that ./student-test could generate the relative raw coverage files.
Why can't the CmakeLists.txt do the same thing?
