I always use (3).
I repeated what I had done before:
My wxwidgets libraries are located at
M:\wx\wxwidgets-3.1.0\lib\vc_lib
here there are several .lib files like this one
wxmsw31ud_core.lib
1) I deleted all .lib files from that location
2) did a PLplot cmake run with
cmake ".." -G "Visual Studio
14" -DPL_DOUBLE:BOOL=ON -DBUILD_TEST:BOOL=ON
-DCMAKE_CONFIGURATION_TYPES:STRING="Debug"
-DCMAKE_BUILD_TYPE:STRING="Debug" -DBUILD_SHARED_LIBS:BOOL=OFF
-DSTATIC_RUNTIME:BOOL=ON
-DPLD_wxwidgets:BOOL=ON -DwxWidgets_ROOT_DIR:PATH=%WXWIN%
-DwxWidgets_LIB_DIR:PATH=%WXWIN%\lib\vc_lib
-DwxWidgets_CONFIGURATION=mswud -DwxWidgets_EXCLUDE_COMMON_LIBRARIES:BOOL=OFF
> cmake.out.txt 2>&1
where
%WXWIN%
is
M:\wx\wxwidgets-3.1.0
cmake.out.txt is attached and it detected wxwidgets
2) Built the Visual Studio generated solution and got the wxwidgets linking
errors
4) rebuilt wxwidgets libraries at M:\wx\wxwidgets-3.1.0\lib\vc_lib
5) did the same PLplot cmake run
6) Built the Visual Studio generated solution , no errors
I took a look at the PLplot
FindwxWidgets.cmake
module and it seems that there is an attempt to find the wxwidgets libraries
(the actual file names), here
find_library(WX_${LIB}${_DBG}
NAMES
wxbase31${_UCD}${_DBG}_${LIB}
so, not sure exactly what happened, and probably we could leave this
possible non-critical bug for after the release (if it's a bug).
I started using cmake in my projects some months ago, and what I do to
detect libraries is like this,
an example for the JSON jansson library:
find_library(JANSSON_LIBRARY NAMES jansson HINTS
"/data/data127/pvicente/install/jansson-2.9/lib/")
if(NOT JANSSON_LIBRARY)
message(FATAL_ERROR "jansson library not found")
else()
message("-- Found jansson library at: " ${JANSSON_LIBRARY})
endif()
on a typical Unix system where jansson is installed on a standard place I
get this by doing just
cmake ..
-- Found jansson.h header file at: /usr/include
-- Found jansson library at: /usr/lib/i386-linux-gnu/libjansson.so
On a Unix system where I don't have jansson on a standard place , I do the
HINTS option , like
find_library(JANSSON_LIBRARY NAMES jansson HINTS
"/data/data127/pvicente/install/jansson-2.9/lib/")
and I can do also
cmake ..
On a Windows system (or a Unix system) I provide the option
cmake .. -DJANSSON_LIBRARY=/my/path/to/jansson
Here's my Windows call (the path like /C/ is because this is in Git Bash)
cmake
.. -DSTATIC_CRT:BOOL=ON -DJANSSON_INCLUDE:PATH=/C/include
-DJANSSON_LIBRARY=/C/lib/jansson.lib
my library file is actually called (extra _d)
/C/lib/jansson_d.lib
and cmake said
-- Found jansson.h header file at: C:/include
-- Found jansson library at: C:/lib/jansson.lib
then when I build Visual Studio I get
LINK : fatal error LNK1104: cannot open file 'C:\lib\jansson.lib'
my understanding is that
find_library
does not actually detect if the argument is an existent file
Or could be that it does not because I am using the same variable name
JANSSON_LIBRARY
for both the argument of
cmake .. -DJANSSON_LIBRARY
and
find_library(JANSSON_LIBRARY
so , this print
-- Found jansson library at: C:/lib/jansson.lib
is not actually true for this example.
Probably it would be possible to actually detect if the file does indeed
exist, but I did it like this to keep things simple
So, the solution I have for
find_library
assumes that the supplied argument
-DJANSSON_LIBRARY
is a valid file
