# CMake find_package() stops working when CMAKE_SYSTEM_NAME=iOS
This repository contains an [MCVE](https://stackoverflow.com/help/minimal-reproducible-example) for the CMake issue described in:
* https://discourse.cmake.org/t/find-package-stops-working-when-cmake-system-name-ios/4609
* https://gitlab.kitware.com/cmake/cmake/-/issues/23041
## How to run?
Execute `./build.sh` on a macOS computer and watch the output.
You'll see that removing `-D CMAKE_SYSTEM_NAME="iOS"` from CMake's invocation fixes the problem.
## Expected output
```
-- The C compiler identification is AppleClang 11.0.0.11000033
-- The CXX compiler identification is AppleClang 11.0.0.11000033
-- Detecting C compiler ABI info
-- Detecting C compiler ABI info - done
-- Check for working C compiler: /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/cc - skipped

-- Check for working CXX compiler: /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/c++ - skipped

It works!!!
-- Configuring done
-- Generating done
-- Build files have been written to: /Users/benoit/Git/cmake-findpackage-ios-bug/build
```
Notice the `It works!!!` message.
## Actual output
```

CMake Error at CMakeLists.txt:5 (find_package):
By not providing "FindThePackage.cmake" in CMAKE_MODULE_PATH this project
has asked CMake to find a package configuration file provided by
"ThePackage", but CMake did not find one.
Could not find a package configuration file provided by "ThePackage" with
any of the following names:
ThePackageConfig.cmake
thepackage-config.cmake
Add the installation prefix of "ThePackage" to CMAKE_PREFIX_PATH or set
"ThePackage_DIR" to a directory containing one of the above files. If
"ThePackage" provides a separate development package or SDK, be sure it has
been installed.
