net/tigervnc: Switch to options helpers

[meta]

Summary

• Cleanup unnecessary CFLAGS
• Switch shell substitution to $()
• Switch to ImageMagick 7
• s/XORG_WRKDIR/XORG_WRKSRC/ as the variable actually refers WRKSRC
• Use relative path to refer other ports as many other ports do that

If you wanted OPTIONS_SINGLE, it would look like this:

OPTIONS_DEFAULT= IM7

OPTIONS_SINGLE=  IMAGEMAGICK
OPTIONS_SINGLE_IMAGEMAGICK=  IM6 IM7

IMAGEMAGICK_DESC=  Imagemagick version for generating [whatever it is it generates here]
IM6_DESC=  Imagemagick 6
IM7_DESC=  Imagemagick 7
IM7_BUILD_DEPENDS= convert:graphics/imagemagick7
IM6_BUILD_DEPENDS= convert:graphics/imagemagick6

net/tigervnc/Makefile

bsd.port.options.mk shouldn't be necessary anymore

This should just be:
GNUTLS_CMAKE_BOOL= ENABLE_GNUTLS

Similarly,

PAM_CMAKE_BOOL=   ENABLE_PAM
VIEWER_CMAKE_BOOL =  BUILD_VIEWER

etc.

This seems the port always depends on IM. IM is required only VIEWER option is ON. How can I define nested options?

[adamw]

Ah, I missed that.

You could use OPTIONS_RADIO instead and do OPTIONS_RADIO= VIEWER, VIEWER_IM7 / VIEWER_IM6. Otherwise I agree here that it's not worth it.

Switch to OPT_CMAKE_BOOL

You're missing an E here.

[meta]

fix typo and remove unnecessary bsd.port.options.mk

[adamw]

Those changes look good to me! Good work here. I think you're making a good choice to just leave the IM dependency fixed at 7. Do give it some build testing to make sure that CMAKE_BOOL is behaving the way you want it to.

[meta]

I've already confirmed CMAKE_BOOLs behaves fine, thanks!
