| | | #Imported Targets |
|---|
| | | #^^^^^^^^^^^^^^^^ |
|---|
| | | # |
|---|
| | | #This module provides the following imported targets, if found: |
|---|
| | | # |
|---|
| | | #``license_generator::lcc`` |
|---|
| | | # The lcc executable |

| | | # |
|---|
| | | #If lcc is not found this module will try to download it as a submodule |
|---|
| | | #Git must be installed. |

| | | #``LCC_LOCATION`` Hint for locating the lcc executable |
|---|
| | | # |

| | | #Result Variables |
|---|
| | | #^^^^^^^^^^^^^^^^ |

| | | #This will define the following variables: |
|---|
| | | # |
|---|
| | | #``LCC_FOUND`` |
|---|
| | | # True if the system has the Foo library. |

| | | #Cache Variables |
|---|
| | | #^^^^^^^^^^^^^^^ |
