Hi
I'm learning how to use hierarchical directories in CMake and am trying to
get an example to work that I saw on YouTube. The example isn't doing what
I expect so I would be grateful for some help in understanding why.
I am running CMake 3.10.2 on Ubuntu 18.04 (Microsoft WSL) and using make.
I have a project called 'cmake-good' that should build library
'libsay-hello.a' and executable 'cmake-good'.
Here's the directory tree (excluding CMake artifacts which I don't think I
need to show):
├── CMakeLists.txt
├── build
│ ├── CMakeCache.txt
│ ├── CMakeFiles
│ ├── Makefile
│ ├── cmake_install.cmake
│ ├── hello-exe
│ │ ├── Makefile
│ │ ├── cmake-good
│ └── say-hello
│ ├── Makefile
│ └── libsay-hello.a
├── hello-exe
│ ├── CMakeLists.txt
│ └── main.cpp
├── say-hello
├── CMakeLists.txt
└── src
└── say-hello
├── hello.cpp
└── hello.hpp
Here are the CMakeLists.txt files:
1) Top level CMakeLists.txt:
cmake_minimum_required(VERSION 3.10)
project(MyProject VERSION 1.0.0)
add_subdirectory(say-hello)
add_subdirectory(hello-exe)
2) hello_exe/CMakeLists.txt:
add_executable(cmake-good main.cpp )
target_link_libraries(cmake-good PRIVATE say-hello)
3) say-hello/CMakeLists.txt:
add_library(
say-hello
src/say-hello/hello.hpp
src/say-hello/hello.cpp
)
target_include_directories(say-hello PUBLIC
"${CMAKE_CURRENT_SOURCE_DIR}/src")
My problem is that I expect to see:
hello-exe/cmake-good
say-hello/libsay-hello.a
but I see:
build\hello-exe\cmake-good
build\say-hello\libsay-hello.a
Why is that?
