# TribitsOldSimpleExampleApp
|
||
|
|
|
||
|
|
This simple example project `TribitsOldSimpleExampleApp` is a raw CMake
|
||
|
|
project that pulls in libraries from a few packages from
|
||
|
|
[`TribitsExampleProject`](../TribitsExampleProject/README.md) using just
|
||
|
|
`find_package(TribitsExProj REQUIRED COMPONENTS ...)` but uses the old
|
||
|
|
specification for using an installed TriBITS project (i.e. through CMake
|
||
|
|
variables `<Project>_LIBRARIES`, `<Project>_INCLUDE_DIRS`, and
|
||
|
|
`<Project>_TPL_INCLUDE_DIRS`).
|
||
|
|
|
||
|
|
After building and installing TribitsExampleProject under
|
||
|
|
`<upstreamInstallDir>`, then configure, build, and test
|
||
|
|
`TribitsOldSimpleExampleApp` with:
|
||
|
|
|
||
|
|
```
|
||
|
|
cmake \
|
||
|
|
-DCMAKE_PREFIX_PATH=<upstreamInstallDir> \
|
||
|
|
<base-dir>/TribitsOldSimpleExampleApp
|
||
|
|
|
||
|
|
make
|
||
|
|
|
||
|
|
ctest
|
||
|
|
```
|
||
|
|
|
||
|
|
This project can be instructed to use the non-namespaced old deprecated
|
||
|
|
targets by adding the CMake cache var:
|
||
|
|
|
||
|
|
```
|
||
|
|
-D TribitsOldSimpleExApp_USE_DEPRECATED_TARGETS=ON
|
||
|
|
```
|
||
|
|
|
||
|
|
This will generated deprecated warnings with newer versions of TriBITS. (This
|
||
|
|
is to demonstrate and test these deprecated non-namespaced targets and to
|
||
|
|
demonstrate how to remove the deprecated warnings in a downstream customer
|
||
|
|
CMake project.)
|
||
|
|
|
||
|
|
NOTE: The modern version of this project using the modern CMake targets
|
||
|
|
produced by `TribitsExampleProject` is
|
||
|
|
[`TribitsSimpleExampleApp`](../TribitsSimpleExampleApp/README.md). Comparing
|
||
|
|
the `CMakeLists.txt` files in these two projects (e.g. [here](CMakeLists.txt)
|
||
|
|
and [here](../TribitsSimpleExampleApp/CMakeLists.txt)) demonstrates the
|
||
|
|
simplifications afforded by the namespaced modern CMake targets.
