We do not need to support IRIX anymore, so drop relevant parts. In particular, the `CMAKE_THREAD_PREFER_PTHREAD` is frequently confused with `THREADS_PREFER_PTHREAD_FLAG`. Also remove references to the IRIX-specific options and results from other modules and tests.

FindDCMTK
|
|
---------
|
|
|
|
Find DCMTK libraries and applications
|
|
|
|
The module defines the following variables::
|
|
|
|
DCMTK_INCLUDE_DIRS - Directories to include to use DCMTK
|
|
DCMTK_LIBRARIES - Files to link against to use DCMTK
|
|
DCMTK_FOUND - If false, don't try to use DCMTK
|
|
DCMTK_DIR - (optional) Source directory for DCMTK
|
|
|
|
Compatibility
|
|
^^^^^^^^^^^^^
|
|
|
|
This module is able to find a version of DCMTK that does or does not export
|
|
a *DCMTKConfig.cmake* file. It applies a two step process:
|
|
|
|
* Step 1: Attempt to find DCMTK version providing a *DCMTKConfig.cmake* file.
|
|
* Step 2: If step 1 failed, rely on *FindDCMTK.cmake* to set `DCMTK_*` variables details below.
|
|
|
|
|
|
`Recent DCMTK
|
|
<http://git.dcmtk.org/web?p=dcmtk.git;a=commit;h=662ae187c493c6b9a73dd5e3875372cebd0c11fe>`_
|
|
provides a *DCMTKConfig.cmake* :manual:`package configuration file
|
|
<cmake-packages(7)>`. To exclusively use the package configuration file
|
|
(recommended when possible), pass the `NO_MODULE` option to
|
|
:command:`find_package`. For example, `find_package(DCMTK NO_MODULE)`.
|
|
This requires official DCMTK snapshot *3.6.1_20140617* or newer.
|
|
|
|
|
|
Until all clients update to the more recent DCMTK, build systems will need
|
|
to support different versions of DCMTK.
|
|
|
|
On any given system, the following combinations of DCMTK versions could be
|
|
considered:
|
|
|
|
+--------+---------------------+-----------------------+-------------------+
|
|
| | SYSTEM DCMTK | LOCAL DCMTK | Supported ? |
|
|
+--------+---------------------+-----------------------+-------------------+
|
|
| Case A | NA | [ ] DCMTKConfig | YES |
|
|
+--------+---------------------+-----------------------+-------------------+
|
|
| Case B | NA | [X] DCMTKConfig | YES |
|
|
+--------+---------------------+-----------------------+-------------------+
|
|
| Case C | [ ] DCMTKConfig | NA | YES |
|
|
+--------+---------------------+-----------------------+-------------------+
|
|
| Case D | [X] DCMTKConfig | NA | YES |
|
|
+--------+---------------------+-----------------------+-------------------+
|
|
| Case E | [ ] DCMTKConfig | [ ] DCMTKConfig | YES (*) |
|
|
+--------+---------------------+-----------------------+-------------------+
|
|
| Case F | [X] DCMTKConfig | [ ] DCMTKConfig | NO |
|
|
+--------+---------------------+-----------------------+-------------------+
|
|
| Case G | [ ] DCMTKConfig | [X] DCMTKConfig | YES |
|
|
+--------+---------------------+-----------------------+-------------------+
|
|
| Case H | [X] DCMTKConfig | [X] DCMTKConfig | YES |
|
|
+--------+---------------------+-----------------------+-------------------+
|
|
|
|
(*) See Troubleshooting section.

|
|
Legend:
|
|
|
|
NA ...............: Means that no System or Local DCMTK is available
|
|
|
|
[ ] DCMTKConfig ..: Means that the version of DCMTK does NOT export a DCMTKConfig.cmake file.
|
|
|
|
[X] DCMTKConfig ..: Means that the version of DCMTK exports a DCMTKConfig.cmake file.
|

Troubleshooting
|
|
^^^^^^^^^^^^^^^
|
|
|
|
What to do if my project finds a different version of DCMTK?
|
|
|
|
Remove DCMTK entry from the CMake cache per :command:`find_package`
|
|
documentation.
