# Tests add_custom_command and add_custom_target support
|
|
|
|
This test demonstrates add_custom_command and add_custom_target support in cmkr.
|
|
|
|
```toml
|
|
#
|
|
# There are two forms of add_custom_command in CMake:
|
|
# 1. Output form: generates files that can be consumed by other targets
|
|
# 2. Target form: runs commands at build time for a specific target (pre-build, pre-link, post-build)
|
|
