How to set an environment variable in maven depending on the OS

I am fairly new to maven. I have setup a pom.xml which defines a profile for running my unit tests. I am trying to set Path environment variable. The env variable name is Path for Windows and LD_LIBRARY_PATH for Linux. I don't want to keep on changing these env. variable names depending on the OS. How should I achieve this?

<profile>
        <id>integration-tests</id>
        <build>
         <plugins>
            <plugin>
                <groupId>org.eclipse.tycho</groupId>
                <artifactId>tycho-surefire-plugin</artifactId>
                <version>${tychoVersion}</version>
                <configuration combine.self="override">
                    <argLine>${tycho.testArgLine} ${global.test.vmargs} ${bundle.test.vmargs}</argLine>
                    <forkMode>${bundle.test.forkMode}</forkMode>
                    <useUIHarness>${bundle.test.useUIHarness}</useUIHarness>
                    <useUIThread>${bundle.test.useUIThread}</useUIThread>
                    <environmentVariables>
                      <!--For windows change LD_LIBRARY_PATH to PATH-->
                        <LD_LIBRARY_PATH>${dependenciesDir}${path.separator}{env.LD_LIBRARY_PATH}</LD_LIBRARY_PATH>

                    </environmentVariables>
                </configuration>
            </plugin>
        </plugins>
        </build>

    </profile>

Profile activation might help here. Remove the <environmentVariables> config from the integration tests profile. Then add the profiles below, tweaking the <activation> sections to meet the specific requirements. You do not need to explicitly enable these profiles on the command line; Maven will activate the right profile based on which system is running the build.

<profile>
  <id>windows-tests</id>
  <activation>
      <os>
        <family>Windows</family>
      </os>
  </activation>
  <build>
     <plugins>
        <plugin>
            <groupId>org.eclipse.tycho</groupId>
            <artifactId>tycho-surefire-plugin</artifactId>
            <version>${tychoVersion}</version>
            <configuration>
                <environmentVariables>
                    <PATH>${dependenciesDir}${path.separator}{env.PATH}</PATH>
                </environmentVariables>
            </configuration>
        </plugin>
    </plugins>
    </build>
</profile>
<profile>
  <id>linux-tests</id>
  <activation>
      <os>
        <family>Linux</family>
      </os>
  </activation>
  <build>
     <plugins>
        <plugin>
            <groupId>org.eclipse.tycho</groupId>
            <artifactId>tycho-surefire-plugin</artifactId>
            <version>${tychoVersion}</version>
            <configuration>
                <environmentVariables>
                    <LD_LIBRARY_PATH>${dependenciesDir}${path.separator}{env.LD_LIBRARY_PATH}</LD_LIBRARY_PATH>

                </environmentVariables>
            </configuration>
        </plugin>
    </plugins>
    </build>
</profile>

PhantomJS; If I set a variable inside page.evaluate(), how can I access the value of that variable outside of page.evaluate()
