Rather than give you the answer to a contrived example, here is the way you would generate an executable using <a href="https://github.com/westes/flex" rel="nofollow noreferrer">flex</a> and <a href="http://www.gnu.org/software/bison/" rel="nofollow noreferrer">bison</a>

<pre><code>find_package(BISON)
find_package(FLEX)

BISON_TARGET(MyParser parser.y ${CMAKE_CURRENT_BINARY_DIR}/parser.cc)
FLEX_TARGET(MyScanner lexer.l ${CMAKE_CURRENT_BINARY_DIR}/lexer.cc)
ADD_FLEX_BISON_DEPENDENCY(MyScanner MyParser)

include_directories(${CMAKE_CURRENT_BINARY_DIR})
add_executable(Foo
 Foo.cc
 ${BISON_MyParser_OUTPUTS}
 ${FLEX_MyScanner_OUTPUTS})
target_link_libraries(Foo ${FLEX_LIBRARIES} ${BISON_LIBRARIES})
</code></pre>

The CMake find packages for bison/flex are included in the default installation, so this is cross platform.

In general to create an output that will later be used as an input you can use the <a href="http://www.cmake.org/cmake/help/cmake-2-8-docs.html#command:add_custom_command" rel="nofollow noreferrer">add_custom_command</a> function. If you use an output from the custom command as an input to a library or executable, then CMake knows to run your custom command before compiling the sources for the library/executable target.

The following line has Typo

<pre><code>FLEX_TARGET(MyScanner lexer.l ${CMAKE_CURRENT_BIANRY_DIR}/lexer.cc)
</code></pre>

BIANRY should be spelled as BINARY. 

Note: CMake Documentation has this typo there as well. ( in 2.8.0, this is fixed in 2.8.10 documentation)..

I require the syntax of a CMAKE macro that generates .cc and .h files from a tool like lex/yacc. 

Could someone please show me the syntax for the following contrived example: 

say I have a file y.cc that depends on x.cc and x.h, the two files mentioned are generated by tool z_tool from file x.z. What would the syntax for this be ? 

For this example assume that y.cc will be turned into a static library, and as I am quite new to CMAKE the full CMakellist.txt for this contrived example would be very helpful.I'm looking for a portable solution as the tools I am using are available on windows as well as UNIX variants.

我需要一个CMAKE宏的语法，该宏从像lex/yacc这样的工具中生成.cc和.h文件。有谁能给我看看下面这个设计的例子的语法：假设我有一个依赖于y.cc和x.h的文件x.cc，上面提到的两个文件是由x.z文件中的工具z_tool生成的。这样做的语法是什么？对于这个示例，假设y.cc将被转换为一个静态库，并且由于我对C...
