# Demo repository for CMake-based projects
This repository contains a template tree of sources for building / installing / exporting / importing libraries and executables with CMake.
## Project 1
* `Lib1`: standalone
* `Main1`: links with `Lib1`
#### Build and install:
```sh
cd Project1
mkdir build && cd build
cmake -DCMAKE_INSTALL_PREFIX=$(pwd)/../../install/Project1 ..
make && make install
CMAKE_PREFIX_PATH=$CMAKE_PREFIX_PATH:$(pwd)/../../install/Project1
```
#### Run:
```sh
./Main1
```
## Project2
(TODO: switch to `COMPONENTS`)
* `Lib2`: standalone
* `Lib3`: links with `Lib2`
* `Main2`: links with `Lib3`
This project shows how to handle a library project split in different parts.
Two use cases are considered:
1. `Main2`: is an in-tree executable used as unit test of the `Lib2` and `Lib3`
2. `Project3`: is an external project that imports and links against these libraries
#### Build and install:
```sh
cd Project2
mkdir build && cd build
cmake -DCMAKE_INSTALL_PREFIX=$(pwd)/../../install/Project2 ..
make && make install
CMAKE_PREFIX_PATH=$CMAKE_PREFIX_PATH:$(pwd)/../../install/Project2
```
#### Run:
```sh
./Main2
```
## Project3
* `Main3`: links with either the installed `Lib1` library, and the `Lib3` component
The import of `Lib1` is straightforward.
In the `Lib3` case, `find_package(Lib3)` should look for an installed `Lib3` _and_ also its
dependencies (`Lib2`), setting implicitly all the required `include_directories()`.
#### Build and install:
```sh
cd Project3
mkdir build && cd build
cmake ..
make
```
#### Run:
```sh
./Main3
```
