== System installation ==
This library is header only. So you can either copy `include/cxxopts.hpp` to `/usr/include` or `/usr/local/include`, or add `include` to your search path.
== Building the examples and tests ==
It is preferable to build out of source. Make a build directory somewhere, and then
do the following, where `${CXXOPTS_DIR}` is the path that you checked out `cxxopts`
to:
cmake ${CXXOPTS_DIR}
make
You can use another build tool, such as ninja.
cmake -G Ninja ${CXXOPTS_DIR}
ninja
To run the tests, you have to configure `cxxopts` with another flag:
cmake -D CXXOPTS_BUILD_TESTS=On ${CXXOPTS_DIR}
make
make test
== Using cxxopts in tipi.build projects ==
`cxxopts` can be easily used in [tipi.build](https://tipi.build) projects simply by adding the following entry to your `.tipi/deps`:
```json
{
"jarro2783/cxxopts": { "@": "v3.0.0" }
}
```
To try this you can run the following command in `/src` (change the target name appropriately to `linux` or `macos` or `windows`):
```bash
tipi . -t <target>
./build/linux-cxx17/bin/test_package -v
```
To develop `cxxopts` using tipi run the following command at the root of the repository:
```bash
tipi . -t <target> --test all -v
```
