* Clarify auto-dereference cases in if() command (#11701)Brad King2011-01-171-20/+14
| | | | | | Show "<variable|string>" explicitly in if() case documentation whenever auto-dereferencing occurs. Reference its presence from the explanation at the bottom.
* Replace misleading example in the if() documentation (#10773)Brad King2011-01-141-34/+25
| | | | | | | | | | | | | | Remove the example explained by the misleading phrase "CMake will treat it as if you wrote". This was originally added by commit a73071ca (modified the if command to address bug 9123 some, 2009-06-12). Later related information elsewhere in the documentation was corrected and made precise by commit cb185d93 (Fix if() command and CMP0012 OLD/NEW behavior, 2009-10-27) but the misleading example was not corrected. Replace the example with a correct one that more directly covers the case that typically surprises newcomers. Avoid recommending a "correct" way to write code because this behavior is always specific to each case. Also update the main documentation of the behavior to be more explicit.
* Fix if() command and CMP0012 OLD/NEW behaviorBrad King2009-10-271-10/+18
| | | | | | | | | | | | | | The commit "modified the if command to address bug 9123 some" changed the if() command behavior with respect to named boolean constants. It introduced policy CMP0012 to provide compatibility. However, it also changed behavior with respect to numbers (like '2') but did not cover the change with the policy. Also, the behavior it created for numbers is confusing ('2' is false). This commit teaches if() to recognize numbers again, and treats them like the C language does in terms of boolean conversion. We also fix the CMP0012 check to trigger in all cases where the result of boolean coersion differs from that produced by CMake 2.6.4.

* Convert CMake to OSI-approved BSD LicenseBrad King2009-09-281-14/+9
| | | | | | | This converts the CMake license to a pure 3-clause OSI-approved BSD License. We drop the previous license clause requiring modified versions to be plainly marked. We also update the CMake copyright to cover the full development time range.

* ENH: Better error message for unclosed blocksBrad King2009-01-211-1/+0
| | | | | | This centralizes construction of the error message for an unclosed logical block (if, foreach, etc.). We record the line at which each block is opened so it can be reported in the error message.
* ENH: Refactor function blocker deletionBrad King2009-01-201-2/+1
| | | | | | | | | When a function blocker decides to remove itself we previously removed it at every return point from the C++ scope in which its removal is needed. This teaches function blockers to transfer ownership of themselves from cmMakefile to an automatic variable for deletion on return. Since this removes blockers before they replay their commands, we no longer need to avoid running blockers on their own commands.
* ENH: Add version comparison to if() commandBrad King2008-09-101-0/+5
| | | | | | Provide VERSION_LESS, VERSION_EQUAL, and VERSION_GREATER operators in the if() command. This simplifies component-wise comparison of version numbers in the form "major[.minor[.patch[.tweak]]]".
* ENH: Add if(TARGET) commandBrad King2008-08-201-0/+2
| | | | | | | | | | It is useful to be able to test if a target has been created. Often targets are created only inside conditions. Rather than storing the result of the condition manually for testing by other parts of the project, it is much easier for the other parts to just test for the target's existence. This will also be useful when find-modules start reporting results with IMPORTED targets and projects want to test if a certain target is available.

* ENH: Add "if(POLICY policy-id)" option for IF command.Brad King2008-03-201-0/+3
| | | | | | | | | | | - This will help projects support multiple CMake versions. - In order to set a policy when using a newer CMake but still working with an older CMake one may write if(POLICY CMP1234) cmake_policy(SET CMP1234 NEW) endif(POLICY CMP1234) - Note that since CMake 2.4 does not have if(POLICY) supporting it will also require using "if(COMMAND cmake_policy)"
