# vcpkg_from_sourceforge

Download and extract a project from sourceforge.

## Usage:
```cmake
vcpkg_from_sourceforge(
    OUT_SOURCE_PATH SOURCE_PATH
    REPO <cunit/CUnit>
    [REF <2.1-3>]
    SHA512 <547b417109332...>
    FILENAME <CUnit-2.1-3.tar.bz2>
    [DISABLE_SSL]
    [NO_REMOVE_ONE_LEVEL]
    [PATCHES <patch1.patch> <patch2.patch>...]
)
```

## Parameters:
### OUT_SOURCE_PATH
Specifies the out-variable that will contain the extracted location.

This should be set to `SOURCE_PATH` by convention.

### REPO
The organization or user and repository (optional) on sourceforge.

### REF
A stable version number that will not change contents.

### FILENAME
The local name for the file. Files are shared between ports, so the file may need to be renamed to make it clearly attributed to this port and avoid conflicts.

For example, we can get the download link:
https://sourceforge.net/settings/mirror_choices?projectname=mad&filename=libmad/0.15.1b/libmad-0.15.1b.tar.gz&selected=nchc
So the REPO is `mad/libmad`, the REF is `0.15.1b`, and the FILENAME is `libmad-0.15.1b.tar.gz`

For some special links:
https://sourceforge.net/settings/mirror_choices?projectname=soxr&filename=soxr-0.1.3-Source.tar.xz&selected=nchc
The REPO is `soxr`, REF is not exist, and the FILENAME is `soxr-0.1.3-Source.tar.xz`

### SHA512
The SHA512 hash that should match the archive.

### PATCHES
A list of patches to be applied to the extracted sources.

Relative paths are based on the port directory.

### DISABLE_SSL
Disable ssl when downloading source.

### NO_REMOVE_ONE_LEVEL
Specifies that the default removal of the top level folder should not occur.
