# Introduction
|
||
|
|
For building OR-Tools as a CMake standalone project, you can read the following instructions.
|
||
|
|
|
||
|
|
This project should run on GNU/Linux, MacOS and Windows.
|
||
|
|
|
||
|
|
# C++ Project Build
|
||
|
|
1. Get the source code and change to it.
|
||
|
|
```sh
|
||
|
|
git clone https://github.com/google/or-tools.git
|
||
|
|
cd or-tools
|
||
|
|
```
|
||
|
|
|
||
|
|
2. Run CMake to configure the build tree.
|
||
|
|
```sh
|
||
|
|
cmake -S. -Bbuild -G "Unix Makefiles" -DBUILD_DEPS=ON
|
||
|
|
```
|
||
|
|
note: To get the list of available generators (e.g. Visual Studio), use `-G ""`
|
||
|
|
|
||
|
|
3. Afterwards, generated files can be used to compile the project.
|
||
|
|
```sh
|
||
|
|
cmake --build build -v
|
||
|
|
```
|
||
|
|
|
||
|
|
4. Test the build software (optional).
|
||
|
|
```sh
|
||
|
|
cmake --build build --target test
|
||
|
|
```
|
||
|
|
|
||
|
|
5. Install the built files (optional).
|
||
|
|
```sh
|
||
|
|
cmake --build build --target install
|
||
|
|
```
|
||
|
|
|
||
|
|
# Technical Notes
|
||
|
|
## Managing RPATH
|
||
|
|
Since we want to use the [CMAKE_BINARY_DIR](https://cmake.org/cmake/help/latest/variable/CMAKE_BINARY_DIR.html) to generate the wrapper package (e.g. python wheel package) as well as be able to test from the build directory.
|
||
|
|
We need to enable:
|
||
|
|
```cmake
|
||
|
|
set(CMAKE_BUILD_WITH_INSTALL_RPATH TRUE)
|
||
|
|
```
|
||
|
|
And have a finely tailored rpath for each library.
